RATCHET-DRILL FRAME.

SPECIFICATION forming part of Letters Patent No. 415,198, dated November19, 1889.

Application filed May 25, 1889. Serial No. 312,132. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE E. HEINBAOH, a citizen of the United States,and a resident of Lewistown, in the county of Mifflin and State ofPennsylvania, have invented certain new and useful Improvements inRatchet- Drill Frames; and I hereby declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to make and use the invention.

This invention relates to ratchet drill frames.

Heretofore by the use of the ordinary drillframes employed forboringholes in railroadrails,&c., great inconvenience has been caused by thedelay caused to trainsincident to their passage over the rails while theframe is being used. Furthermore, difficulty has been experienced by thenecessity of using one particular kind of ratchet-drill "in connectionwith the frame, and, finally, it has been difficult to perform theoperation of drilling either on the outside of the rail, between thetracks, 011 the top of the ties, or on either side of the same by oneand the same tool.

In order to obviate this and numerous other" objections, I have inventeda drill-frame capable of being used with any ratchet-drill one which maybe adjusted to fit any rail; one that may be used between the tracks aswell as on the outside of the rail; one that, when used between thetracks, may serve the dual purpose of a brace and of a drill, thusmaking it perfectly safe for trains to pass over the rails at any timeand at any speed by simply lowering the handle of the ratchet-drill,and, finally, one that can be attached to any part of a rail, eitherover or between the ties.

I have illustrated the invention in the accompanying drawings, in whichlike letters of reference indicate corresponding parts in all thefigures, and in which Figure 1 represents a top plan view of my frame,showing the parts in operative position, the frame being attachedbetween the tracks. Fig. 2 represents a side view of the same, and Fig.3 represents a detail view of the various operative parts in theirrelative proportions.

In the drawings, A represents a straight bar, preferably made ofcast-steel, and, say, about twenty-eight inches long, two inches wide,and one inch thick, designed to be placed lengthwise of the tie, eitheron top or upon one side of the same, and to pass underneath the rail tobe drilled. The bar has at one end an offset a, extending into which, onthe face of the bar from which the offset projects, is an angulardepression or mortise a, there being, if desired, upon the same face aseries of indentations a and at one side another series of indentationsa The bar is placed in position, with the offset and described faceupward. Upon the bar are slid three heads B, B, and B preferably ofsteel, the head B being designed to receive the end of a ratchet-drill,preferably in a projection b, with overhang, which serves a purposepresently to be explained, and the heads B and B being designed to beclamped against the Web of the rail, to present means for keeping theframe steady while in use. The head B is movable longitudinally on thebar A in order to accommodate ratchet-drills of various lengths, and isprovided with any suitable device to permit its adjustment on the bar Aand retain it firmly in the desired position when adj ustedsuch as aset-screw bto be turned into one of the indentations a on the bar. Thehead B also is movable longitudinally on the bar A, to be moved to andfrom the web of a rail, and is provided with any suitable device topermit its adjustment on the bar A, and retain itfirmly in the desiredposition when adj usted-such as a set-screw b to be turned into one ofthe indentations a on the side of the bar A. The head 13 designed totake over the other side of the web of the rail, forms an abutmentagainst the offset a, there being a key or wedge inserted in the mortisebetween this head and the offset, the key serving the double purpose oftightening up from this end, and by a nick in the head and by themortise extending under the offset holding it steadily in place.

In some cases I may dispense with the head B and bring the offset a ofthe bar A against the rail, thus forming an adequate clamp with the headB; or, using the heads B and 13*, I

may dispense with the wedge and bring the head B flush against theoffset of the bar.

O represents another bar, preferably of refined iron, the purpose ofwhich is, by means of bar D, to hold the rail which is being drilled inproper relative position to the adjacent rail. This bar 0 hasa lug orshoulder at 0, preferably about six inches from the screw-threaded end0, forming abrace to rest against the rail, and, in connection with nut0 taking upon the screw-threaded end 0' after the said end is introducedinto the hole already made in the rail to retain the bar 0 in properposition. The opposite end of Cis also screw-threaded for a distanceequal to about half its entire length, designed to receive the nuts 0and 0", the purposes of which are hereinafter set forth.

The bar D, preferably of steel, and,'say, about twenty inches long bythree-fourths inch thick by two inches wide, is designed to be used indrilling successive holes after the first has been bored. This bar D isprovided with a circular opening or eye at one end, to be entered by thescrew-threaded portion of O farthest from the rail, and is held againstdisplacement by means of the nuts 0 and 0 The bar D is further providedwith a series of indentations d for receiving the end of the drill,these indentations serving the purpose of preventing the drill frombecoming dislodged.

The operation of drilling the first hole is as follows: Having slid thehead B upon the bar A, the bar A is then placed in position under therail, with the offset a and the mortise a upon the upper face. The headB is then slid upon the bar A until it impinges upon the web of therail, and is retained in position by means of set-screw b being turnedinto one of the indentations a on A, and the wedge or key being insertedin the mortise of A and the nick in head B the bar is firmly andsecurely attached to the rail. I now slide head B upon the bar A; thenplace the drill in position, one end resting against the rail and theother against the head B, after which I adjust head B until it pressestightly against the end of the drill, and then retain the head inposition by turning the set-screw 1) into one of the indentations a onbar A. By this operation the drill is securely held against dislodgment.

In drilling successive holes the operation is as follows: The bar Ahaving been placed and retained in position, as above described, I placethe bar C in position by inserting the screw-threaded end 0 into thehole already bored in the rail until the lug or shoulder 0 formedthereon fits snuglyagainst the rail, and then screw nut 0 into position,whereby the bar (3 is held rigidly in place. I then screw nut 0 upon theopposite end to that upon which nut c is placed and introduce theperforated end or eye of bar D upon this end of bar 0, allowing it toimpinge against nut 0 after which I screw nut c on this end of bar C.Bar D, it is evident, will by its own weight fall against the upper faceof bar A. I then introduce one end of the drill into one of theindentations d on the bar D, after which head B is slid upon bar A untilit presses against the bar D, when it is retained in position byset-screw b, the overhang on head B preventing the bar D from beingraised out of its proper position. The nuts 0 and c then being adjustedto bring the barD in a position parallel to the rail, the device is in aposition ready to be operated.

Having thus fully described my invention, what'I claim as new, anddesire to secure by Letters Patent. is
